蓄水

Soil erosion is one of the most important ecological environment problems in our country, which results in land resource destroy, soil degradation, land productivity decrease, water pollution, river and water storage works aggradation, flood, avalanche, mudrock flow and menace to the life and wealth of people, and so on.

土壤侵蚀问题是目前我国面临的主要生态环境问题之一，严重的水土流失不仅破坏土地资源、降低土壤肥力、制约粮食生产增长，还污染水环境、淤积河道和蓄水工程，导致洪水、崩塌和泥石流等灾害频繁发生、威胁人民的生命财产等。

To improve the purple soil storage capacity, to prevent soil erosion in hunan province, the choice of HengYangXian 20o purple soil slope, setting Guan waste land, grassland, natural forest and grassland and agrimony slight composite 4 processing, the water treatment performance and its mechanism, and the results show that, compared to the purple soil LuoDe HuangShanPo ground implement agrimony and three-dimensional planting trees for 1-2 years later, reduce soil bulk density 0.10 g/cm3 0.09 ~, soil porosity, permeability of soil moisture 14.01% increase rate increase 2.20 ~ 2.29 times.

为提高紫色土蓄水能力，防止水土流失，在湖南省衡阳县选择20o 左右的紫色土荒山坡地，设置祼地、自然草地、龙须草地和龙须草与林地复合4 个处理，比较分析各处理贮水性能及其改良机理。结果表明，与裸地相比，在紫色土荒山坡地上实行龙须草与林木立体种植1～2 年后，土壤容重降低0.09～0.10g/cm3，土壤总孔隙度增加14.01%，土壤水分渗透速率提高2.20～2.29 倍。

The water contents in 1m soil layer of eight vegetation types in Yuanmou dry and hot valley in rainy season(August 2 to September 2) were measured and analyzed.These eight vegetation types are Pinus caribaea plantation,Pinus caribaea+Dodonaea viscosa plantation,Albizzia kalkora natural regeneration forest;Dodonaea viscosa+Tephrosia candida plantation,eucalyptus plantation,grassland,waste land and expansive soil.

通过对元谋干热河谷区加勒比松人工林、加勒比松+车桑子人工混交林、山合欢天然更新林、车桑子+山毛豆人工混交林、桉树人工林、草地、荒坡、膨胀土8种植被类型林地1 m土层内不同层次雨季(8月2日~9月2日)土壤水分含量的分析研究得出：在雨季8种植被类型林地土壤的水分含量均较低，因其土壤的物理性能较差，故蓄水保水能力也较差；各植被类型林地土壤的有机质、养分含量均极低，按照土壤养分含量分级标准，各植被类型林地土壤的养分含量均在6级以下。

Especially the anabranch water level is raisen great and the flow speed slow down obviously for holded up by the Yangtze River, and the rate of water eutrophication is raisen. The thesis chose the typical branch river, Xiaojiang river, to sample and research the eutrophication degree , and discover that the eutrophication of branch river are serious.

本论文主要选择了典型消落带断面，分析了浮游生物种类，并以典型流域——小江流域，对该流域的消落带水体的富营养化程度进行了调查、采样、监测和分析，并运用模糊数学理论建立了评价模型，对消落带水体的富营养化程度进行了评判，发现蓄水后长江支流富营养化现象较为严重。

This method required vast quantities of water, and so extensive aqueduct and tank systems were oftentimes constructed.

这种方式需要大量的水，所以经常需要建造大型的输水管道和蓄水系统。

Afew hundred million gallons of water will also be pumped out of the local aquifer each year.

每年将有几个亿加仑的水从当地的地下蓄水层抽取上来。

Since the completion of the Three Gorges Dam however, the water has become calm."Goddess", China's first cabin cruiser was named after GoddessPeak. Passenger on board have a fine view of the picturesque scenery and a small boat guide the large vessel.

三峡大坝蓄水以后，水面上升，水流平缓，这里已经是一片高峡出平湖的平和景象。1981年，以三峡中著名景观"神女峰"命名的"神女"号在长江下水，"神女"号的主要观光线路就是长江三峡。20多年前，"神女"号的游客在长江上看到了令人震撼的美景。

Base on the field experiments in Huaibei Plain of Anhui Province, this article analyzed the feasibility of water storage in main drainage canal and effect of regulation for surface runoff, soil and groundwater, and put forward technique parameters and mode of the water storage facility.

通过在安徽淮北平原的大田原型试验，分析了利用农田排水大沟进行控制蓄水的可行性及其对地表径流、地下水和土壤水的调控效果，提出了平原区依托大沟控制蓄水的农田水资源调控系统成套技术参数和模式。

Li Yong'an, Three Gorges Project welcomed in three milestones in 2003, namely water filling of the reservoir, operation of the ship lock and power production of the generating unit; and further in September 2005, the 14 sets of hydro-turbine generating unit (700MW each) of the left-bank powerhouse were all connected on-line for power production; and in May 2006, approximate 10 months ahead of the preliminary design schedule and 2 years ahead of the expectation of the flood control performance, the Three Gorges Dam was completed and fully reached to its designed crest elevation of 185m, able to impound water with the whole structure of dam.

历任清江水电开发公司总经理兼湖北省人民政府副秘书长，中国三峡总公司副总经理。在李永安先生的领导下，长江三峡工程于2003年实现了蓄水、通航和发电三大目标，2005年9月左岸电站14台700MW水轮发电机组全部投产发电，2006年5月三峡主体工程大坝全线到达185米设计坝顶高程，具备全线挡水能力，工期比初步设计工期提前约10个月，提前两年发挥防洪能力。2006年10月，三峡水库蓄水至156米。

Based on previous researches on the Three Gorges of the Yangtze River, twenty selected typical landslides and rockfalls are studied by classification.

中文摘要：在前人相关研究的基础上，选择三峡工程库区20处典型崩塌、滑坡体进行分类研究，分析三峡水库蓄水时和蓄水后，由于水位变动所产生的各种作用力，以及这些作用力可能给库区的崩塌、滑坡体带来的影响。
